中文摘要：

针对传统方法在评价加权网络节点重要度时存在的不足,综合考虑节点位置和邻接节点的贡献信息,提出节点重要度评价矩阵方法。基于此,发展一种改进的网络重构双层优化模型,上层模型以最大化系统发电量为目标、以非黑启动机组获得启动功率的时间为优化变量,确定非黑启动机组的恢复顺序;下层模型以恢复路径平均节点重要度最大为目标确定发电机节点的恢复路径,并通过调节系数改变线路权重中线路电容与操作时间的比重,以避免恢复路径所需时间过长而导致待恢复机组无法尽快恢复的问题。新英格兰10机39节点系统的仿真结果说明了所发展的模型和方法的基本特征。

英文摘要：

Aiming at the deficiency of traditional methods in evaluating the node importance of weighted network,a method comprehensively considering the node location and adjacent node contribution is proposed based on the node importance evaluation matrix,according to which,an improved bi-level network reconfiguration optimization model is developed. Its upper-level optimization model takes the maximum generation output of system to be restored as its objective and the time of non black-start generator obtaining the startup power as the optimization variable to determine the startup sequence of black-start generators,while its lower-level optimization model takes the maximum average node importance of restora-tion path as its objective to determine the restoration path of generator node. An adjusting coefficient is employed to change the proportions of line capacitance and operation time in the line weight for avoiding the restoration time of restoration path is too long to quickly restart the generator to be recovered. Simu-lative results of the New England 10-unit 39-bus power system demonstrate the basic features of the developed model and method.
